What does it mean "does not work"? What do you expect them to do and what do they do instead?

For me the Home and End move cursor to the beginning and end of a line, respectively, as expected.

Using the in-built text editor, the "page-up" and "page-down" respond correctly but "home" and "end" do not work. I'm on a Windows 10 machine and running the latest version 5.9.3. I have tried this on a different Windows 10 machine with the same behavior.
